what is polycarbonate plastic

It can typically be formed at room temperature without cracking or breaking, similar to aluminum sheet metal. PC for 3D printing is usually limited to a white color. Their drawbacks are: acrylic can crack/shatter under impact and polycarbonate is easier to scratch. Injection moldable polycarbonate might include other additives such as mold release agents that lubricate the material during processing. Although deformation may be simpler with the application of heat, even small angle bends are possible without it. Polycarbonate is mainly used for electronic applications that capitalize on its collective safety features. Polycarbonate, like other plastics, starts with the distillation of hydrocarbon fuels into lighter groups called “fractions” some of which are combined with other catalysts to produce plastics (typically via polymerization or polycondensation). Polycarbonate definition is - any of various tough transparent thermoplastics characterized by high impact strength and high softening temperature. Polycarbonate plastic is more dimensionally stable than acrylic over a wide temperature range. It can also serve as a dielectric in high-stability capacitors. In summary the benefits are: acrylic is stiffer, shinier, more scratch resistant and cheaper than polycarbonate which is bendier and virtually unbreakable.
